Do you need clearance before running again?
Yes, twice. First, clearance from your obstetrician or GP at the postnatal review, usually around six weeks. Ask specifically about impact exercise, because "you can exercise" and "you can run" are different answers. Second, a pelvic-floor and strength screen, ideally by a women's health physiotherapist; KKH, NUH and private clinics all offer this. A personal trainer can coach the strength work and the progression, but cannot assess your pelvic floor internally, and should say so. The postnatal fitness guide covers the first six weeks; this page picks up from there.
Why should running wait until about 12 weeks?
Because running is high impact and the pelvic floor, abdominal wall and connective tissue are still recovering well past the six-week mark. The return-to-running guidance published in the British Journal of Sports Medicine and the 2024 international consensus statement both recommend a minimum of 12 weeks postpartum plus a graded programme, and research on real timelines found the median first run was at about 12 weeks. Each running stride lands with roughly two to three times bodyweight; doing that thousands of times on tissue that cannot yet hold tension is the most common route to leaking that lasts years. Waiting costs you a few weeks. Rushing can cost far more.
Twelve weeks is a floor, not a promise. A caesarean, a third- or fourth-degree tear, an instrumental delivery, significant blood loss or a pelvic organ prolapse diagnosis all push it later, and your doctor or physio is the person who says by how much. So does how the pregnancy went: someone who ran until 30 weeks tends to return faster than someone who stopped in the first trimester, simply because the strength base is more recent. Neither is a competition. The date on the calendar matters less than passing the screen below.
What should you be able to do before your first run?
The physio guidance uses a simple screen. If any item causes leaking, heaviness, pain or doming, you are not ready yet, and the fix is strength and pelvic-floor work, not more waiting.
- Walk 30 minutes briskly without pelvic symptoms.
- Single-leg balance for 10 seconds each side, eyes open.
- Single-leg squat, 10 each side, with control.
- Jog on the spot for one minute, then forward bounds, hops and single-leg hops, 10 each.
- Single-leg calf raises, bridges and sit-to-stands, 20 each side, without symptoms.
If you fail an item, that is information, not a verdict. Failing the calf raises means calves and the ankle need four to six weeks of work; leaking on the hops means the pelvic floor needs a physio and a strength block; wobbling on the single-leg balance means glutes and feet. Retest every two weeks. Most women who fail at 12 weeks pass by 16-18 with targeted work, which is a far better outcome than starting to run at 12 and stopping at 14 with a problem.
What does a walk-jog progression look like?
| Week | Session | Move on when |
|---|---|---|
| 1 | Walk 4 min, jog 1 min, repeat 4 times | No leaking, heaviness or pain during or the next day |
| 2 | Walk 3 min, jog 2 min, repeat 4 times | Same, and you recover fully by the next session |
| 3 | Walk 2 min, jog 3 min, repeat 4 times | Same |
| 4 | Walk 1 min, jog 4 min, repeat 4 times | Same |
| 5 | Jog 10 min, walk 2 min, jog 10 min | Same |
| 6 | Jog 20-25 min continuous, easy pace | Then add no more than 10 percent a week |
Keep two strength sessions a week running alongside this. Glutes, calves, single-leg work and a core that can brace under load are what make the running hold up; the running itself does not build them. A sensible pair of 40-minute sessions covers split squats, single-leg Romanian deadlifts, hip thrusts, calf raises, rows and carries, at 3 sets of 8-12, with breathing and pelvic-floor work at the end. Run and lift on different days where you can; a run the morning after a heavy leg session is where symptoms tend to show up.

What are the signs to stop?
Leaking urine, a dragging or heavy feeling in the pelvis, pain in the pelvis, lower back or caesarean scar, doming or coning down the midline of your belly, and bleeding that restarts or gets heavier. None of these are things to run through. They are a reason to drop back a week in the progression, and if they persist across two sessions, to book a women's health physio. Diastasis recti is not itself a ban on running, but an abdominal wall that cannot hold tension when you land is, so it gets assessed and trained first.
How do you make this work in Singapore?
- Heat: run before 8am or after 7pm. Sleep-deprived and possibly breastfeeding, you overheat faster than you used to, so carry water even for 20 minutes.
- Route: park connectors, East Coast Park and the Bishan-Ang Mo Kio Park loop are shaded and flat. Avoid the void-deck steps and kerb-hopping of an HDB estate until hops are pain-free.
- Pram running: only once you are running 20 minutes continuously without symptoms. Pushing changes your arm swing and posture; keep it to flat, smooth paths.
- Feeding: feed or pump before you go and wear a supportive sports bra. Moderate exercise does not affect supply.
- Sleep: after a night with under five hours, swap the run for a walk. The progression waits; an injury does not.
Where does a coach fit in?
A coach builds the strength base at home, runs the screen with you, and manages the progression so you do not jump from week two to week five because you felt good one morning. What a coach cannot do is examine your pelvic floor or diagnose why you are leaking; that is a physio's job, and a good coach will refer you rather than reassure you. If you would prefer a woman, say so when you message; see female personal trainer, or the full prenatal and postnatal service.
